Biological activity: Recombinant mouse Granzyme B supplied in its inactive form. Once the mouse Granzyme B is activated by active mouse Capthepsin C/DPPI, it is able to cleave the peptide substrate t-Butyloxycaronyl-Ala-Ala-ThioBenzyl ester (Boc-AAD-SBzl) in the presence of 5,5'Dithio-bis (2-nitrobenzoic acid) (DTNB)1,2, with an activity > 3000 pmol/min/μg.

- 背景
- Granzyme B is a serine protease expressed by cytotoxic T cells (CTL) and NK cells. Its main function is to induce cell death to eliminate harmful targets such as allogeneic, virally infected, and tumorous cells. This is evident by the fact that CTLs from mice deficient of granzyme B exhibit a profound defect in inducing rapid DNA fragmentation and apoptosis in target cells. Following receptor-mediated conjugate formation between CTL or NK and their target cell, granzyme B enters the target via endocytosis, and subsequently activates multiple protein substrates to induce apoptosis. Most circulating CD56+ CD8- NK cells, and approximately half of circulating CD8+ T cells, coexpress both granzyme A and B. In contrast, few circulating CD4+ T cells express granzymes A or B. Activation of CD8+ and CD4+ T cells induces substantial expression of granzyme B, but not granzyme A. Besides CTL and NK, evidence has shown that the distribution of human granzyme B has a broader spectrum of cells including CD34+ hematopoietic progenitor cells, keratinocytes, basophils, mast cells, plasmacytoid dendritic cells, and B cells. Although its role in cytotoxic lymphocyte-mediated apoptosis is well established, granzyme B can also degrade extracellular matrix proteins and alter inflammation if present in the extracellular milieu. These findings suggest that granzyme B can function as an activation molecule with potentially important immunoregulatory functions. In addition, it was shown that expression of granzyme B is elevated in acute coronary syndrome and acute myocardia infarction, indicating that granzyme B could be a factor involved in cardiovascular diseases.
